My invention relates to improvements in con- In ,order that the invention be more clearly densing apparatus. understood an example embodying the same has In the chemical industry frequently condensing been illustrated in the accompanying drawing apparatus or condensing towers or the like are showing a condensing tower and a cooling chamneeded.
